ENVELOP.

Specification of Letters Patent.

Patented Nov. 16, 1920.

Application filed January 7, 1919. Serial No. 269,978.

To all whom it may concern:

Be it known that I, GEORGE FRANCIS HOGAN, a citizen of the United States re- 'siding at Chicago, inthe county of-(lb ok,

State of Illinois, have invented .certain new and useful Improvements in Envelops; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to envelops of the non-sealing type, and it proposes an envelop of the character indicated which may be closed insuch a wayas to efi'e'ctively protect its contents while. still permitting the envelop to be sentthrough the mail with merchandise postage.

.According to the invention, the envelop is constructed of a single blank of paper or other suitable sheet material, the component parts of which are folded together, and one of such parts, forming an end flap, is secured in the usual way to the back of the envelop, while the other end is closable bya flap formed by two extensions from the top and bottom flap joined at their edges, whichis itself folded and held in closed position by a tongue which is formed on the body or front end of the envelop, and folded over and detachably fastened .to the joined edges of the top and bottom flaps which form reinforcements. In this way, the envelop is securely closed I and its contents thereby protected,'without, however, utilizing'a permanent seal of any character, the construction and arrangement of the tongue enabling it to be, detached from the reinforcement formed "by the edges of the top and bottom flaps when occasion arises.

The accompanying drawing shows one form which the invention may take in practice, and therein:

Figure 1 is a plan. view of the blank from which the envelop is constructed; Fig. 2 is a front View of the envelop in closed condition; Fig. 3 is'a rear view thereof; and Fig. 4 is an enlarged detail section on line 4-4 of Fig. '3.

Referring more particularly to the drawings, the improved envelop is constructed The body 5 forms the front of the envelop and, as usual, receives name and address of the person to whom the envelop'is to be sent. The back of the envelop, instead of being formed by a single member, is formed of the two flaps 7 and 8, which are folded over against the rear face of the body 5, with their free longitudinal; edges overlapping and forming a reinforcement, one or the other of these flaps having applied to it a suitable adhesive to hold them in the position indicated. The end flap 6 is then folded over and asted to the flaps 7 and 8, thereby closing the envelop atone end.

The other end of the envelop is closed by a flap which, instead of being of unitary construction, and forming an integral part of the front member or body 5, as is ordi top and bottom flaps 7 and 8, respectively, 4

and form continuations of one end thereof, as illustrated in Fig. 1. 'When the latter flaps are folded over and pasted together as above described, the extensions 9 and 10 are likewise brought into overlapping relation, and they likewise are fastened together by the adhesive, forming a thickened portion in the way of a reinforcement already referred to. It is intended that this compound flap 9, 10 be folded against the outer or front face of the body 5, and to permit this disposition of said flap, while at the same time providing means for detachably holding it in folded or closed position, the adjacent ends of the body are furnished with an integral fastening tongue 11. The latter, as will be understood, projects beyond the body 5 for a distance at least as great as the width of the flap 9, L0, and the body is slit at the points where it is joined by the tongue, as indicated at 12 in Fig. 1, thereby approximately doubling the length of the tongue. Consequently, the compound flap can be folded over between the tongue and the body, and the tongue then folded, in turn, over against the rear flap 7 as represented in Figs. 3 and 4, thus the flap and the tongue present at certain portions of the envelop and at the edge fixed to the flap 7 and inserted through a,

metal eyelet 14 secured to the end portion of the tongue, the exposed portions of the arms of the clip being spread out against the tongue in the ordinary manner.

It Will be understood from the foregoing, that the envelop may be readily closed and fastened in a manner to effectively protect its contents against loss, While at the same time avoiding the use of a permanent seal of any character, and that, when desired, the tongue may be readily disengaged from the fastener 13, after which the end flap 9, 10 may be folded back to permit access to the contents of the envelop.

I claim as my invention An envelop, comprising, in combination, a body provided at one end With a fia and also provided with flaps at its top an bottom edges, the top and bottom flaps being folded against the inner face of the body in overlapping relation and forming a reinforced portion, and the end flap bein folded over and secured on the outer ace of said overlapping: top and bottom flaps, means on said top and bottom flaps for re leasably closing the other end of the envelop by. being folded over the exterior thereof, fastening "nieanscarried by said reinforced portion, and an integral fastening tongue on said body and formed in part therefrom and adapted to be folded over said closing means and detachablv fastened tosaidfireinforced portion, substantially as described.

In testimon whereof I aflix m signature.

GEO GE FRANCIS OGAN.
